No accounts, fully offline, and free CSV exports: I built a gear maintenance tracker for those who hate subscription traps

Hey r/diving ,

Like many of you, I’ve invested a significant amount of money into my dive kit. But keeping up with life-support maintenance schedules where brands recommend servicing every year (or two) or every 100 dives, whichever comes first - quickly became a mess of fading dive-shop stickers, mental math, and a clunky spreadsheet that I kept forgetting to update.

Since I couldn't find a clean, dedicated utility for this, I decided to build one. It’s called ServiceDeco, and it is fully live on the iOS App Store.

I wanted to build this specifically around the no-nonsense, practical needs of active divers, so I wrote it under some strict personal rules:

• 100% Offline-First: There are no cloud servers. There's no account sign-up, no "login with Facebook", and no ads. It works perfectly on an offshore charter boat or deep in a cave with zero cellular service. Your data stays strictly on your device.
• "Whichever Comes First" Monitoring: You can set dynamic thresholds in both days and dive counts (e.g., 2 years / 100 dives). The dashboard monitors both metrics automatically and highlights exactly when a piece of gear is approaching overdue status.
• Full Cylinder Compliance: Built-in regional presets (US, EU, UK, AU) to track your Hydro and Visual Inspection (VIP) cycles. 
• Track Any Kit: Easily log history (including cost, shop, kits used, and custom notes) for regulators, rebreather O2 cells, BCDs, computers, lights, and custom parts.
• Absolute Data Ownership: You can export your entire service logs/history to a standard CSV anytime for free, forever. No feature paywalls.

If you are setting up your gear prep for the season and want to try it out, it's completely free to download https://apps.apple.com/us/app/servicedeco-dive-gear-service/id6777115227

Would love to get your honest feedback. Are there specific parameters, cell tracking constraints, or native templates you’d want to see added to make this your go-to gear locker companion?

Safe diving!
